SUBMERSIBLE WATER TOY AND RELATED METHOD OF USE FIELD OF THE INVENTION The present invention relates generally to aquatic devices. More particularly, the present invention relates to a submersible water toy for buoyantly supporting a portion of the user's weight when used in a pool, ocean, lake or other body of water.

In the specification the term "comprising" shall be understood to have a broad meaning similar to the term "including" and will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. This definition also applies to variations on the term "comprising" such as "comprise" and "comprises".

BACKGROUND OF THE INVENTION Various types of competition and recreation relating to stunt- based activities have recently experienced increased popularity. While this popularity is not age limited, most of the popularity has been with children and young adults. These competitions and recreational activities include both aquatic activities and land based activities. Participants in these activities generally ride on equipment and perform stunts of various difficulty based on their experience level.

The aquatic competitions and recreational activities include water skiing. As is well known, the water skier is pulled behind a boat and performs various maneuvers ranging from passing back and forth across the boat wake to flips and jumps. A related aquatic activity involves the use of a knee-board.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

With initial reference to the environmental view of Figure 1, a submersible water toy constructed in accordance with the teachings of a preferred embodiment of the present invention is illustrated and generally identified at reference 10. The water toy 10 is shown submersed in a pool of water 12. It will be understood by those skilled in the art that the teachings of 00

O

the present invention are equally applicable for oceans, lakes or other bodies z of water. A user 14 is shown positioned on the submersible water toy 10. The weight of user 14 is buoyantly supported by the toy 10 such that at least a portion of the user is below the level of the water or submersed.

With continued reference to the environmental view of Figure 1 and additional reference to Figures 2 and 3, the submersible water toy 10 of the present invention will be further described. The submersible water toy 10 may 00 include a core or main body portion 16. The core 16 may be constructed of a foam material. In one particular application, the core 16 is constructed of ethylene vinyl acetate. In other applications, the core can be constructed of expanded polystyrene foam. Those skilled in the art will readily appreciate that various other types of materials can be employed within the scope of the present invention.

The main body portion 16 is shown to include a central section or portion 18 having an upper surface 20 and a lower surface 22. The upper surface 20 defines a deck portion for directly supporting the feet of the user 14 (see Figure 1, for example). The lower surface 22 is buoyantly supported by the water.

As most particularly shown in Figure 2, the submersible water toy may include cantilevered front and rear ends 24 and 26 which angle upwardly as they extend from the center portion 18. These angled front and rear ends 24 and 26 provide alternate surfaces for engaging the feet of the user 14 as the user performs various stunts. The submersible water toy 10 of the present invention may be alternatively constructed without these angled front and rear ends 24 and 26.

In one particular application, the submersible water toy 10 has an ethylene vinyl acetate core and a length of approximately 31 inches (78.8cm), a width of approximately 8 inches (20.3cm) and a thickness of approximately 2 00 6

O

inches (5.1cm). In another particular application, the submersible water toy has an expanded polystyrene core and a length of 29 inches (73.7cm), a width of 8 inches (20.3cm) and a thickness of 2 inches (5.1cm). These dimensions, however, are merely exemplary. In this regard, the dimensions can be modified depending on factors including but not limited to the buoyancy of the particular material incorporated to construct the toy; the weight of the intended user; and the particular stunts or tricks intended to be performed on the toy.

Based on all these factors, an optimal design of the submersible water toy 00 provides enough buoyancy to support at least a portion of the user's weight.

As shown in the environmental view, the user 14 is supported while performing a stunt such that the water level is at his chest. In most applications, the buoyancy of the submersible water toy 10 is low enough that larger children and adults will be able to pin the toy 10 to the pool bottom while in shallow water. The size of the toy 10 can be modified to accommodate different user weights. Without the user 14, the toy will float to the surface of the pool 12 for easy retrieval.

Turning now to the cross-sectional view of Figure 4, a first alternative embodiment of a submersible water toy constructed in accordance with the teachings of the present invention is illustrated and generally identified at reference character 110. The submersible water toy 110 is similarly constructed to the toy 10 of the preferred embodiment to include a foam core 16. Distinct from the preferred embodiment, the submersible water toy 110 additionally includes a plastic shell 112. The plastic shell 112 provides additional strength and increases the useful life of the toy 110. The remainder of the details of the submersible water toy 110 will be understood to be similar to those details described above in connection with the preferred embodiment.

Turning now to Figure 5, a second alternative embodiment of a submersible water toy constructed in accordance with the teachings of the present invention is illustrated and generally identified at reference character 210. Again, the submersible water toy 210 is similarly constructed to the toy 00 7

O

of the preferred embodiment to include a foam core 16. Distinct from the z preferred embodiment, the submersible water toy 210 additionally includes front and rear ends 112 and 114 that inwardly and upwardly curve as they extend from the main body portion 18. The curved ends 112 and 114 define convex surfaces 116 and 118, respectively, for opposing the sides of the feet of the user 10. These surfaces may facilitate the performance of particular tricks or stunts by the user 10. The remainder of the details of the osubmersible water toy 210 will be understood to be similar to those details 00 described above in connection with the preferred embodiment.

Turning now to Figure 6, a third alternative embodiment of a submersible water toy constructed in accordance with the teachings of the present invention is illustrated and generally identified at reference character 310. In this particular embodiment, the submersible water toy 310 of the present invention is modified to be able to readily accommodate users of various sizes. As noted above, one critical aspect of the present invention allows the user to be suitably supported within the water for the performance of tricks or stunts. The submersible water toy 310 includes a main body portion 18 that is similar to that described above. The submersible water toy 310 further includes a plurality of buoyant panels 312 that may be selectively attached to the main body portion 18 depending on the particular buoyancy required of the toy 310. In the embodiment illustrated, the submersible water toy 310 is shown to include two panels 312. Those skilled in the art will appreciate that any particular number of panels may be incorporated within the scope of the present invention. The panels 312 are removably secured to the main body portionl8 with elastic bands 314. Alternative manners of releasably attaching the panels 312 may also be employed.
